Flash to HTML5 conversion gone wrong

Hi, the company I work for wants to use display banners in their campaign. I've created a bunch of animated ads to use in AdWords. First we used GIF's, however the 5 fps limit was a bit annoying so instead we went ahead and created flash ads.

When we upload them the flash ad looks normal, however the HTML5 ad seemed to have some odd anti-aliasing problem. See below in the html5 version, when the image stops moving it corrects itself slightly. Does Google do that to improve performance? Is there anything we can do to fix this for mobile devices?

Flash version:

HTML5 version:

Quick edit: we are using vectors in Flash, but the same issue appears if we use bitmap images in the animations.

Hello, Mark. I think there's some resizing involved in there as well, which leads to that anti-aliasing. These two animations don't seem to have the same size (when they're stopped).

You can try creating an animation for only one size and making sure the widths and heights are exact pixels which do not need to be resized to see if the problem persists.

So don't use points or mms in Flash but rather pixels (if it's possible, I can't remember) and work with a standard size (say 300 x 250) and then check the 300 x 250 HTML ad alone. See if the problem still occurs and please let us know as well.

Hi Calin, currently remaking the ads from the ground up with some changes. Though the images used in the previous ads where all the exact same size across all keyframes. Will update later if the new ads worked.

Re: Flash to HTML5 conversion going wrong

I'm sure they were exactly the same size across keyframes. But if you start with one template and allow AdWords to generate several HTML5 ads by resizing elements from a master template I'm afraid some strange anti-aliasing might happen. Good luck!
